Abstract:
The ability of plants to appropriately respond to the soil nutrient availability is of primary importance for their development and to complete their life cycle. Deciphering these multifaceted adaptive mechanisms remains a major challenge for scientists to date. Recent technological breakthroughs now enable to assess the dynamism and complexity of these processes at unprecedented resolution. In this review, we present some of the most recent findings on the involvement of histone modifications, histone variants and DNA methylation in response to nutrient stresses as well as discussing the potential roles these chromatin changes could serve as priming or as trans-generational stress memory mechanisms.

01:10Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
